Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drain trap that connects to a drain pipe installed under the floor of a bathroom or the like to seal the water.

[Conventional technology]

Conventionally, a drainage trap has been placed under the floor of a washing area such as a bathroom in order to prevent the release of unpleasant odors from the drainage pipe.

This drainage trap has a cylindrical main body 50 buried under a floor surface 51 as shown in FIG.
A drain pipe 52 is inserted into the main body 50, and the upper end opening of the drain pipe 52 is covered with a bowl body 53 having a lower end opening to form a bent flow path for sealing water.

Further, a disc-shaped lid 54 with a drainage hole 55 is removably placed on the upper end of the main body 50 so as to be on the same level as the floor surface 51, thereby making it possible to clean deposits inside the main body 50.

In such a drainage trap, both the cylindrical main body 50 and the lid 54 are made of metal, and the lid 54 is plated for appearance and rust prevention.

[Problem that the invention attempts to solve]

However, if the lid 54 is made of a metal material, even if it is plated, its surface will be scratched and rusted during long-term use, making it unsuitable for sanitary equipment and shortening its useful life. Further, there is a problem that the metal lid 54 and the surrounding tiles 56 are made of different materials, giving rise to a sense of discomfort.

Furthermore, since rectangular tiles 56 are usually laid on the floor surface 51, if the lid 54 is disc-shaped, the surrounding tiles 56 must be cut into an arc shape on site to match the outer shape of the lid 54. Another problem is that the construction work is complicated.

The purpose of the present invention is to improve the durability of the drain trap cover, maintain harmony with the surrounding tiles, and facilitate the tile construction work.

[Means and actions for solving problems]

The present invention is a drainage trap in which a lid is placed on the upper end of the main body that communicates with the drain pipe, and this main body is buried and fixed under the floor to form the drainage section together with the drain pipe. It is made of shaped tiles, which maintains harmony with the surrounding tiles, improves durability, and facilitates the tile construction work.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Fig. 1 is a sectional view of the main part of the drain trap 1, and Fig. 2 is a plan view of the same.This drain trap 1 has a structure in which a lid 4 is placed on a flange 3 at the upper end of a cylindrical body 2, as in the conventional case. A drain pipe 5 whose upper end is open is connected to the lower end of the main body 2, and a bowl body 6 covering the drain pipe 5 from above is connected to a support 7.

The bowl body 6 together with the drain pipe 5 forms a trap T that seals the upper end of the drain pipe 5 to a water-sealing level, and prevents the release of strange odors from the drain pipe 5 by sealing the water.

The lid 4 is made of tile (for example, natural stone, ceramic, or porcelain with a glazed surface), has drainage holes 10 penetrating the entire surface, and is made of elastic rubber or the like on the lower surface that comes into contact with the flange 3. A buffer band 11 is attached.

The lid 4 may have any shape such as a disc shape that matches the shape of the flange 3 of the main body 2 or a rectangular shape in which each side length is larger than the outer diameter of the flange 3.

In the case of a rectangular lid 4, if it has the same shape as the laying tiles 20 placed on the bathroom floor (for example, a square with a side of 100 mm) as shown in FIG. 3, the joints 21 will be the same as the surrounding tiles 20. It can be laid out in an orderly manner with intervals.

Therefore, work such as scraping the outer periphery of the laid tiles 20 around the lid 4 along the outer shape of the lid 4 is no longer necessary.
Moreover, it can be constructed in a state that maintains harmony with the surrounding laid tiles 20.

Furthermore, if the surface of the lid 4 is treated to match not only the shape but also the hue and pattern of the surrounding tiles 20, the layout can be aesthetically pleasing without creating an unnatural feeling. When drawing, there is no discontinuity at the 4 parts of the lid.

FIG. 4 is a cross-sectional view showing an example of the structure of another lid 4. This is one in which a reinforcing synthetic resin layer 12 is integrated on the lower surface of the lid 4, which prevents cracking of the tile lid 4 and also prevents the lid 4 from cracking. This synthetic resin layer 12 can also serve as a buffering effect like the buffer band 11 shown in FIG.

The synthetic resin layer 12 is formed into a plate shape using, for example, FRP as a material and is attached to the lower surface of the lid 4, or is integrated into the lid 4 by lining treatment.

As described above, since the lid 4 is made of tiles, it can be used hygienically without rusting, etc., and can be constructed in harmony with the surrounding tiles 20 without damaging the hue or pattern. In addition, when the lid 4 is made of tiles made of ceramic or the like, even if dirt adheres to the surface, it can be easily wiped off, and sanitary facilities such as a bathroom can always be kept clean.

In this embodiment, a bathroom drainage section has been described, but the present invention can also be used for floor drainage sections of other sanitary facilities.

[Effect of idea]

The lid of this invention is made of tiles, which prevents rust and makes it easy to remove dirt, so it can be used hygienically at all times, and the layout can be constructed in harmony with the tiles on the surrounding floor. play.
